Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.

It's fine to celebrate success but it is more important to heed the lessons of failure.

Success and failure are both part of life. Both are not permanent.

The great question is not whether you have failed, but whether you are content with failure.

I don't believe in failure. It is not failure if you enjoyed the process.

Failure is unimportant. It takes courage to make a fool of yourself.

We have forty million reasons for failure, but not a single excuse.

The only real failure in life is not to be true to the best one knows.

My great concern is not whether you have failed, but whether you are content with your failure.

I think that failure by your own standards is certainly a form of success.
